Definitions

  • the present invention relates to a polymer layer composite for a security and / or value document and to a method for its production. Furthermore, the invention relates to a security and / or value document which can be produced from the polymer layer composite according to the invention, for example by welding the composite into transparent protective films. Moreover, the invention relates to the use of the security or value document as a credit card, bank card, cash card, customer card, visa card, ID card, identity card, passport or driver's license.
  • Card-shaped data carriers are used, for example, for the identification of persons and / or objects and / or for cashless payment transactions. You have u.a. visually identifiable features that clearly assign them to a person and / or an item and / or a cash or securities account and only allow the owner to identify himself or to dispose of the item or account and arrange for money transfers. For this reason, these data carriers must have security features that make it virtually impossible for unauthorized persons to falsify or falsify the cards, so that abuse can be prevented as much as possible. In addition, a fake should therefore be easily recognizable.
  • Essential security features in the card-shaped data carriers are personalized and / or individualized features that are stored in the data carrier.
  • Personalized features are, for example, passport photos and data of the person to whom the card is associated, such as date of birth, address or identification number in a company, as well as biometric data such as a digitized record of fingerprints or the size, or the person's eye color or affiliation health insurance.
  • Individualized features are data associated with a particular device such as a motor vehicle, a bank account, or a security.
  • Such personalized and / or individualized features are applied individually to the card-shaped data carriers for the person using them. Therefore, the process for their generation must be flexible.
  • methods and apparatus for applying such data to card-shaped media are described in US 6,022,429 A, US 6,264,296 B1, US 6,685,312 B2, US 6,932,527 B2, US 6,979,141 B1 and US 7,037,013 B2, the disclosure of which is hereby incorporated in full in the disclosure of this description , wherein the personalized and / or individualized features include can be applied to the cards by means of inkjet printing technology.
  • High-quality card-shaped data carriers today consist in particular of polycarbonate.
  • Personalization and / or customization of polycarbonate-based cards typically takes place by laser engraving.
  • a laser beam is focused into the material and guided over the material.
  • the laser beam produces pungencies in the interior through pyrolysis, which vary in intensity depending on the laser intensity and duration at the respective points.
  • an image or other graphics or even a lettering or a number and / or letter combination can be generated.
  • it is not possible with this method to produce colored images or graphics and font or number sequences, but only black / white representations. At most, it is also possible to some extent to produce gray tones / levels. Therefore, there has been no lack of further attempts to produce colored representations by means of printing techniques in the maps.
  • the present invention is therefore initially based on the problem that a layer composite with personalized and / or individualized features which have been produced by printing technology can possibly be delaminated or split by unauthorized manipulations, so that it is desirable to find a method , with which this is reliably prevented.
  • the term "pattern” is used in the description and in the claims, this is to be understood as meaning both structured printing in any manner and full-surface printing reproduction graphic print reproduction, such as guilloches or background screening, or alphanumeric characters or a one-dimensional or two-dimensional barcode or emblem, coats of arms, national emblems or any other print reproduction.
  • surface energy means the tendency of the surface in question (the polymer layer surface) to interact with a liquid, such as a printing ink, and the surface energy is low, if only When there are many bonds, the surface of the liquid is not or not readily wettable, and at high surface energy, the surface is well wetted by the liquid ,

  • the patterns of these primary visible print layers are modified by modifying the surface energy of the polymer layers in the print areas prior to the application of the visible print layers in subregions of the surfaces, these subregions likewise forming a pattern (secondary pattern) ,
  • Such a polymer layer composite is produced according to the invention using the following method steps: (a) providing the layers for the polymer layer composite, (b) modifying the surface energy of the layers in the print areas in partial areas of the surfaces of these print areas to form respective secondary patterns, (c) forming (c ') optionally further modifying the surface energy such that another layer of the composite adheres firmly to the further modified surface regions; and (d) optionally, further modifying the surface energy; cohesive bonding of the layers together.
  • the starting point of the present invention is the recognition that novel security elements can be generated in security and / or value documents, if
  • personalized and / or individualized features produced by printing technology can be modified by modifying the surface energy of the layers in the form of a secondary pattern on the printable surface.
  • personalized and / or individualized features are printed in a grid, for example in a grid as in the case of printing by an ink-jet printing method, the individual grid areas of this primary print are changed by the structure of the surface partial areas modified with respect to their surface energy.
  • the printed image of the primary visible pressure is superimposed by the pattern of the surface sub-areas modified with respect to their surface energy: Where the modified surface areas are located, the material of the layer composite does not absorb any printing ink.
  • the surface modification is preferably an increase or decrease in the hydrophilicity or hydrophobicity of the surface in the print areas.
  • the surface areas thus modified have more hydrophilic or hydrophobic properties than the unmodified surfaces. If, for example, a surface region which has essentially hydrophobic properties, thus also assumes a printing ink predominantly water-immiscible, containing solvent, and is therefore printable by this, by increasing the hydrophilicity modified, the absorption capacity for this printing ink is reduced or completely eliminated. Printing ink striking such a portion is diverted to adjacent surface portions.
  • the modified portions of the surfaces can provide secondary latent visible information and the visible print layers provide primary visible information, and the secondary latent visible and primary visible information are superimposed according to the present invention.
  • the modification of the first information takes place in such a way that the entirety of the first information appears unchanged to a first approximation, for example that a photograph has no discernible quality loss.
  • the present invention relates to a composite of polymer layers, which may optionally contain layers of other materials, such as cardboard, paper, textiles, fabrics, knitted fabrics, or so-called prepregs, for the production of security and / or value documents.

  • the lamination temperature can be lowered without jeopardizing the intimate bond of the laminated layers.
  • this is due to the fact that the various polymer layers can no longer be readily delaminated due to the reaction of the respective reactive groups. Because between the polymer layers takes place a reactive coupling, as it were a reactive lamination.
  • the glass transition temperature T 9 of the at least one polymer layer before thermal lamination is less than 12O 0 C (or less than 110 0 C or less than 100 0 C), wherein the glass transition temperature of this polymer layer after the thermal Lamination by reaction of reactive groups of the base polymer of the polymer layer with each other by at least 5 ° C, preferably at least 20 0 C, higher than the glass transition temperature before the thermal lamination.
